Parameters

Federation is a means by which two organizations can set up a trust relationship that facilitates communication between the two groups. When a federation has been established, users in the two organizations can send each other instant messages, subscribe for presence notifications, and otherwise communicate with one another using SIP applications such as Microsoft Communicator "14". Microsoft Communications Server 2010 allows for three types of federation: 1) direct federation between your organization and another; 2) federation between your organization and a public provider; and, 3) federation between your organization and a third-party hosting provider.

Setting up direct federation with another organization involves several tasks. To begin with, you must enable your Access Edge servers to allow federation; for more information, type "Get-Help Set-CsAccessEdgeConfiguration" (without the quote marks) at the windows PowerShell prompt. In addition, the other organization must enable federation with you; federation cannot be established unless both parties agree to the relationship.

Equally important, you must manage two federation-related lists: the allowed list and the blocked list. The allowed list represents the organizations you have chosen to federate with; if a domain appears on the allowed list then (depending on your configuration settings) your users will be able to exchange instant messages and presence information with users who have accounts in that federated domain. Conversely, the blocked list represents domains that you are expressly forbidden from federating with: messages sent from a blocked domain will automatically be rejected by Communications Server 2010.

The Set-CsAllowedDomain cmdlet provides a way for you to modify property values for any domain on the list of allowed domains.

Set-CsAllowedDomain does not return a value or object. Instead, the cmdlet configures instances of the Microsoft.Rtc.Management.WriteableConfig.Settings.Edge.AllowedDomain object.

-------------------------- Example 1 ------------------------

	Copy Code
Set-CsAllowedDomain -Identity fabrikam.com -Comment "Contact: Ken Myer (kenmyer@fabrikam.com)"

The command shown in Example 1 modifies the Comment property for the allowed domain with the Identity "fabrikam.com". This is done by including the -Comment parameter and the appropriate parameter value: "Contact: Ken Myer (kenmyer@fabrikam.com)".

-------------------------- Example 2 ------------------------

	Copy Code
Get-CsAllowedDomain -Filter *fabrikam* | Set-CsAllowedDomain -Comment "Contact: Ken Myer (kenmyer@fabrikam.com)" -MarkForMonitoring $True

The preceding command modifies the Comment and MarkForMonitoring properties for all the allowed domains that have the string value "fabrikam" somewhere in their Identity. To carry out this task, the command first calls Get-CsAllowedDomain and the -Filter parameter; the filter value "*fabrikam*" instructs Get-CsAllowedDomain to return any domain where the Identity includes the string value "fabrikam". (For example, this command returns domains such as fabrikam.com, us.fabrikam.net, and fabrikam-users.org). The filtered collection is then piped to Set-CsAllowedDomain, which modifies for Comment property and sets the MarkForMonitoring property to True ($True) for each item in the collection.

-------------------------- Example 3 ------------------------

	Copy Code
Get-CsAllowedDomain | Where-Object {$_.MarkForMonitoring -eq $False} | Set-CsAllowedDomain -MarkForMonitoring $True

The command shown in Example 3 modifies all the domains on the allowed list that are not currently monitored by Monitoring Server. (That is, all the domains where the MarkForMonitoring property is set to False.) To do this, Get-CsAllowedDomain is called without any additional parameters in order to retrieve a collection of all the domains on the allowed list. That collection is piped to the Where-Object cmdlet, which selects only those domains where MarkForMonitoring is equal to (-eq) False ($False). That filtered collection is then piped to Set-CsAllowedDomain, which sets the MarkForMonitoring property for each domain in the collection to True ($True).

-------------------------- Example 4 ------------------------

	Copy Code
Get-CsAllowedDomain | Where-Object {$_.Comment -eq $Null} | Set-CsAllowedDomain -Comment "Need contact information."

Example 4 adds a generic comment ("Need contact information.") to each domain on the allowed list where the Comment property currently has no value. To carry out this task, the command first calls Get-CsAllowedDomain to retrieve a collection of all the domains on the allowed list. This collection is then piped to Where-Object, which picks out those domains where the Comment property is equal to (-eq) a null value ($Null). That filtered collection is then piped to Set-CsAllowedDomain, which modifies the Comment property for each item in the collection.
